In this first volume of the new History of Medieval Canon Law series, Lotte Kry presents a bibliographical survey of the chronological and systematic canonical collections in the Latin West from the beginnings of Christianity to Gratian"s Decretum (ca. A.D. 1140). Divided into three large chronological periods-Early Medieval, Carolingian, and Gregorian Reform-the book includes a catalogue of early medieval canonistic manuscripts and valuable information about them. For each collection, Kry has described its type and contents, the time and place of compilation, and when possible, its author. In addition, full bibliographies have been provided for each collection.
